Letters-Patent No. 101,417, dated Apr-l 5, 1870.

' IMPROVEMENT IN TOBACCO-PIPES.

MaravThe Schedule referred to in these Letters Patent and making part of the same.

v following is a full and exact description thereof,

My invention relates to means for disposing of the saliva which is liable to flow into the stem.

Receptacles have been before provided for receiving Vthe saliva, and allowing it to be discharged at intervals; but, so far as Lam aware, all have been open to serious objections.

I have invented improvements in the construct-ion and arrangement of the parts, avoiding these difficulties, presenting an appearance not nngraceful, and adding very materially to the value of the pipe. I make my reservoir directly under the bowl of the pipe, so as in appearance to form a part thereof. I isolate two passages extending a considerable distance up the stem toward the mouth, so that the saliva is early disconnected from the current of heated smoke which moves in the opposite direction. I form an angle at the point where the saliva is disconnected from the smoke, and the smoke, from its dilierent nature, turns the angle with facility, whilethe saliva trickles along in its downward and more direct course. And I provide for a perfect isolation, not only of the passages, but also of the material around the passages, so that the heated bowl and heated portion of the pipe shall be separated by a considerable space from the salivapipe and reservoir.

` I will proceed to describe what I consider the best means of carrying out my invention.

The accompanying drawings form a part of this specification. Figures 1 and 2 my improved pipe.

Similar letters of reference indicate corresponding parts in all the figures.

Referring to fig. Y1

-A is the bowl, made of briar-root or other suitable material, in the ordinary vor any approved form.

B B2 is a moderatlycurved pipe, which may correspond, in form and general position, to the ordinary stem of a pipe, but performing in the lower part of its length, B2, a very different function. It is formed in two distinct pieces, the part B being adapted to the mouth by any ordinary or suitable termination or mouth-piece, and being joined to the part B2 hy a small hollow globe, B1.

The parts B and I32 may be joined to the globe B by properly-cut screw-threads, in the obvious manner.

So far as the part B extends, it performs the functions of the corresponding parts of a pipe-stem. Ihe smoke is drawn to the mouth through the interior thereof, and any saliva which ows into it trickles are longitudinal sections through Y a more liberal space for the saliva.

along its under surface against the current of the ascending gaseous matter.

Below the point B1, a new condition obtains, and the saliva alone iows down through the extension B2, which is cool, and entirely isolated from any connection with the. heated gas. In this condition it flows into a suitable reservoir A', which is mounted under but entirely separate `from the main bowl A. It is divided therefrom by a slight space, sufficient to prevent any considerable transmission of heat, but not suliicient to prevent its appearing at a little distance as a part of the same bowl. This reservoir A' is joined to the lower part B2 of the pipev by screwthreads, as represented. The material may be the 'same as that ofthe part B?, or different, according to taste or convenience.

The form represented in fig. 2 differs from that in fig. 1 mainly in having a more considerable crook in the auxiliary pipe, and a greater angle at its junction with the other portions of the stem, and in providing In this form of the invention, the plain globular reservoir attached directly to the end of the cool stem B2 is replaced by a nearly cylindrical portion having aglobular reservoir below it. In lig. 1, ther bowl of the pipe appears at a little distance as composed of the ordinary large portion A and a small globe, A', apparently attached, but really isolated under it, while in iig. 2 the bowl A appears with .two swells or additional parts underneath, which arel apparently a portion, but really isolated therefrom. It is vobvious that the reservoir, as also most or all of the other parts, may be subjected to still further modifications of form without 'losing all the advantages of my invention.

The smoke is led from the base of the bowl A by an entirely separate o1 auxiliary stem, I), which may.

run parallel to the part B2, at a little distance therefrom, or may be gracefully curved at its upper end, as represented. lvhateverit-s general contour, I consider it important that its upper end joins to the globe B, or to the equivalent junction of the part-s B B2 at a great angle, as represented. 'l

Upon the formation of a partial vacuum by the smoker in the mouth-piece or upper portion of the pipe B, the atmospheric ai'r heilig excluded entirely from -the parts B2 aud A', the smoke is drawn through the bowl A and the auxiliary pipe D. It flows into` the globe B in the direction represented, and there turns a sharp angle to enter the part B. The smoke easily turns this angle, but the saliva, in trickling down the pipe, is certain to avoid this angle, and to continue down the lower and more direct passage.

The bowl A may be made smaller, and adapted to receive and properly hold a cigar, instead of loose tobacco, if preferred.

My pipe may be used with success without the further improvement or feature which I am now to describe.' From my experience in the use of pipes, and my experiments on this invention, I believe it important to provide against a looseness ofthe screw-threads, which is liable to be experienced, especially after the pipe has been some little time in use. When such a looseness exists, there is always a liability of the anxiliary tube D, and, consequently, of the main bowl A moving out of its direct line over 'the lower parts B2 and A. I wish to make this easily disconnectable, and yet firmly keep their places, except when desired. To eect this, I introduce a glass point, spur, or projection, a, in the top of the saliva-reservoir A', and provide a corresponding recess in the base of the bowl A. The parts arc suiciently elastic to allow them to be swung apart, and thus to unlock or disengage the projection a from the hole in the bowl when it is desired` to unscrew and empty; but, under all ordinary conditions, it retains the parts firmly in their proper relations. The arrangement may be reversed, if preferred, by placing the point a on the bowl A, and provide the recess to receive it in the top of the part A'. I esteem it absolutely essential to the success of' the apparatus that this pointu, however' mounted, shall be of small size, and 'of a material which -is a very slow conductor of heat.

My pipe is necessarily liable, like all others, to some small degree of evaporation of the saliva; but my provision for keeping the vessel cool reduces the amount to an almost' iuappreciable quantity, and my arrangement of the passages and separate tubes avoids any possibility that the small quantity of vapor from the saliva-vessel can flow into the bowl, and moisten, or in any way a'ect the tobacco.

The globe 1?l serves as a condensing and separating chamber, in which the moisture, oily matters, and the eral independent pipes without this adjunct, and itv would be certainly impracticable to otherwise form the connections by screws. lts globular form is not absolutely essential to its utility, but contributes much to its beauty, and gives a tasteful appearance to this portion.

I do not claim a pipe with a reservoir for saliva, nor forming contorted and angular passages for the smoke; nor, again, forming a double stem, except when the stems are separated by an air-space, as represented; but

.I claim-f 1. A tobacco-pipe having the bowl A and salivareceptacle A', connected with the separating-chamber Bl by long and independent tubes B2 and D, when the said separating-chamber is arranged, relatively to the howl and mouth-piece, substantially asshownand de. scribed. j

2. In combination with an independent bowl, A,y and branch pipe D, adapted to turn on the stem B B, as represented, the slender non-conducting projection a', mounted on one of the parts, and adapted to lock into the other,-and be disengaged therefrom, to allow the. opening and emptying ofthe parts, as and for the purposes herein set forth.

In testimony whereof I have hereunto set my name in presence ot' two subscribing witnesses.
